Open Banking as a Commercial Engine for ASPSPs
From Regulatory Compliance to Platform Strategy
Open banking is transitioning from a compliance-driven mandate to a commercially viable platform opportunity. For Account Servicing Payment Service Providers (ASPSPs), the ability to operationalise APIs, payment initiation, and consented data access is increasingly linked to measurable outcomes: reduced transaction costs, faster integration cycles, and new revenue models.
This paper outlines where value is being created today, supported by industry data and market observations, and identifies the strategic shifts required for ASPSPs to move from infrastructure providers to ecosystem enablers.
Market Contest
Adoption of open banking continues to accelerate across the UK and Europe, driven by regulatory frameworks, fintech innovation, and demand for real-time financial services.
Key indicators include:
Millions of active open banking users across the UK and Europe, with sustained growth in API usage (OBIE; UK Finance)¹
Expansion of account-to-account (A2A) payments as a viable alternative to card-based transactions (ECB; UK Finance)²
Increasing expectation for real-time financial interactions among both consumers and businesses (Mastercard; ECB)³
These trends are reshaping expectations of speed, cost, and interoperability within financial services.
Commercial Levers for ASPSPs
Real-Time Data as Infrastructure
Access to consented account data enables faster credit decisioning, improved risk modelling, and more relevant product development. Institutions with robust, well-documented APIs are experiencing increased demand from third-party providers.
Industry studies indicate that API-enabled ecosystems reduce integration timelines significantly, in some cases from weeks to days (Deloitte; Accenture)⁴.
Payment Initiation and Cost Reduction
Payment initiation services reduce dependency on card schemes and intermediaries. A2A payments are frequently cited as 70–90% lower cost than traditional card rails in certain use cases (UK Finance; ECB)².
At scale, this represents a meaningful opportunity for both cost reduction and margin improvement.
Trust, Security, and Regulatory Alignment
Strong Customer Authentication (SCA) and PSD2 frameworks provide a high baseline of trust. When embedded effectively into user journeys, these controls can improve transaction success rates while reducing fraud exposure.
This positions ASPSPs to compete not only on compliance, but on reliability and security as differentiators.
Ecosystem Positioning
ASPSPs increasingly function as central nodes within a network of fintechs, platforms, and third-party providers. Institutions that treat APIs as products — with clear standards, uptime, and support — are more likely to become preferred partners.
This shift moves the ASPSP role from service provider to platform enabler.
Data-Driven Value Creation
Transaction data, when used with consent, enables enhanced personalisation, improved underwriting, and more targeted financial services. Research links these capabilities to higher engagement and conversion rates (McKinsey; Accenture)⁵.
This creates a pathway toward monetisable services beyond baseline compliance.
Operational Efficiency and Revenue Expansion
Standardisation and automation reduce operational overhead, while new commercial models — including premium APIs and embedded finance partnerships — introduce additional revenue streams.
The combined effect is a transition from cost centre to value-generating capability.
Strategic Implications
The gap between compliance and competitive advantage is defined by execution. Leading ASPSPs demonstrate:
High-quality, reliable API infrastructure
Efficient partner onboarding and support
Clear commercial models for API and data usage
Integration of security without friction in user journeys
Institutions that fail to evolve risk remaining utility providers within a value chain increasingly shaped by others.
Open banking is no longer a peripheral capability. It is becoming a core component of how financial services are delivered, integrated, and monetised.
For ASPSPs, the opportunity lies in redefining their role: from compliance-driven infrastructure to commercially driven platform.
